Why does my Audi A4's engine make a loud noise when starting?

My Audi A4 always makes a loud screeching noise when I start it up in the morning. It goes away after a few minutes, but it's quite embarrassing. Is this a common issue? How can I fix it?

It sounds like you may have a worn or loose drive belt. It's a common issue in many vehicles, not just Audis. The good news is that it's a simple and inexpensive fix. You can either tighten or replace the belt yourself or take it to a mechanic for a quick tune-up. I recommend getting it fixed sooner rather than later to avoid any potential damage to your engine.

I experienced the same issue with my Audi A4 and after some research, I found that it could be caused by a faulty tensioner or pulley. These parts are responsible for keeping the belt tight and in place. If it's not the belt itself, I suggest checking these components and replacing them if necessary. It may cost a bit more, but it's worth it for a smooth and quiet engine start.

In my experience, the noise on start-up can also be caused by a low battery. If your battery is old or weak, it may struggle to turn over your engine, resulting in a loud screech. I recommend getting your battery tested and replaced if necessary. In the meantime, try turning off any electrical components (e.g. radio, AC) before starting your car to reduce the load on the battery.
